Unternehmen agieren hierbei als Anbieter von Software-Plattformen, auf denen Drittanbieter Softwarelösungen für den Markt anbieten können.  Etablierte Beispiele sind hierbei sogenannte App-Stores, die z.B. von Google oder Apple angeboten werden.\r\n\r\nBeim Aufbau von Software-Ökosystemen müssen vom Plattformanbieter viele architektonische Entwurfsentscheidungen getroffen werden. Bisher gibt es keine Architekturrichtlinien und -werkzeuge, die den Entwurf einer Ökosystemarchitektur unterstützen. Dadurch fehlt hier systematisches, wiederverwendbares Wissen. Plattformanbieter müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen: Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen. Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach: \r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des Frameworks durchgeführt.","lang":"ger"}],"project":[{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C5","_id":"17"},{"_id":"1","name":"SFB 901: SFB 901"}],"file":[{"relation":"main_file","date_updated":"2022-12-30T22:15:15Z","success":1,"file_size":9125342,"file_name":"Bahar_Schwichtenberg_Thesis.pdf","creator":"bahareh","date_created":"2022-12-30T22:15:15Z","access_level":"closed","file_id":"35069","content_type":"application/pdf"}],"title":"Modeling and Analyzing Software Ecosystems","user_id":"36399","keyword":["Enterprise Architecture","Architectural Design Decisions","Open Platforms"],"status":"public","year":"2021","language":[{"iso":"eng"}],"date_created":"2021-12-13T07:20:33Z","date_updated":"2022-12-30T22:15:37Z","_id":"28683","file_date_updated":"2022-12-30T22:15:15Z","supervisor":[{"first_name":"Gregor","full_name":"Engels, Gregor","last_name":"Engels","id":"107"}],"author":[{"full_name":"Schwichtenberg, Bahar","first_name":"Bahar","last_name":"Schwichtenberg","id":"36399"}],"department":[{"_id":"66"}],"citation":{"ama":"Schwichtenberg B. <i>Modeling and Analyzing Software Ecosystems</i>.; 2021. doi:<a href=\"https://doi.org/10.17619/UNIPB/1-1270 \">10.17619/UNIPB/1-1270 </a>","apa":"Schwichtenberg, B.

For an efficient use of solar and wind energy in an energy system, correct design and sizing of a power system is of high importance and improving or optimizing the process of data obtaining for this purpose leads to higher performance and lower cost per unit of energy. It is essential to have the most precise possible estimation of solar and wind energy potential and other local weather parameters in order to fully feed the demand and avoid extra costs. There are various methods for obtaining local data, such as local measurements, official organizational data, satellite obtained, and reanalysis data. In this paper, the Modern-Era Retrospective analysis for Research and Applications dataset version 2 (MERRA-2) dataset provided by NASA is introduced and its performance is evaluated by comparison to various locally measured datasets offered by meteorological institutions such as Meteonorm and Deutscher Wetterdienst (DWD, or Germany’s National Meteorological Service) around the world. After comparison, correlation coefficients from 0.95 to 0.99 are observed for monthly global horizontal irradiance values. In the case of air temperature, correlation coefficients of 0.99 and for wind speed from 0.81 to 0.99 are observed. High correlation with ground measurements and relatively low errors are confirmed, especially for irradiance and temperature values, that makes MERRA-2 a valuable dataset, considering its world coverage and availability.</jats:p>"}],"doi":"10.3390/en14040882","file_date_updated":"2022-01-06T13:33:09Z","_id":"21265","date_updated":"2022-01-06T13:37:34Z","date_created":"2021-02-23T10:18:05Z","publisher":"MDPI","publication_identifier":{"issn":["1996-1073"]},"year":"2021","language":[{"iso":"eng"}],"status":"public","citation":{"bibtex":"@article{Khatibi_Krauter_2021, title={Validation and Performance of Satellite Meteorological Dataset MERRA-2 for Solar and Wind Applications}, volume={14}, DOI={<a href=\"https://doi.org/10.3390/en14040882\">10.3390/en14040882</a>}, number={4882}, journal={Energies}, publisher={MDPI}, author={Khatibi, Arash and Krauter, Stefan}, year={2021} }","mla":"Khatibi, Arash, and Stefan Krauter. “Validation and Performance of Satellite Meteorological Dataset MERRA-2 for Solar and Wind Applications.” <i>Energies</i>, vol. 14, no. 4, 882, MDPI, 2021, doi:<a href=\"https://doi.org/10.3390/en14040882\">10.3390/en14040882</a>.","short":"A.

The charge sampling technique is mathematically analyzed in detail and compared to conventional switched-capacitor sampling. The mathematical analysis allows to predict the sampler bandwidth as well as the degradation of sampling precision due to analog circuit impairments such as integrator gain error, integration capacitor leakage, hold-mode droop, thermal noise, and clock jitter. Furthermore, design, simulation, and measurement results of an ultra-broadband charge sampler IC in SiGe BiCMOS technology are presented. The charge sampler IC achieves a 1dB bandwidth of 70 GHz. A resolution of better than 5.9 effective number of bits (ENOB) is measured from 0 to 70 GHz at a sampling rate of 5 GS/s. The results suggest that charge sampling using an IHC is a viable concept for ultra-broadband sampling.","lang":"eng"}],"doi":"10.1109/tcsi.2021.3094428","title":"Analysis and Design of a Charge Sampler With 70-GHz 1-dB Bandwidth in 130-nm SiGe BiCMOS","issue":"9","page":"3668-3681","volume":68,"type":"journal_article","publication":"IEEE Transactions on Circuits and Systems I: Regular Papers","department":[{"_id":"58"}],"citation":{"short":"L.

Pulsed laser radiation is used to thermoacoustically excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal plate adhesively joined to a polymeric layer using synthetic resin. The resulting signals are received by a purpose-built piezoelectric transducer. Varying the distance between excitation and detection yields spatio-temporal measurement data, from which the dispersive properties of the propagating waves can be inferred using a two-dimensional Fourier transform, assuming the plates to act as coupled waveguides. Coupled multi-layered waveguides show an effect referred to as <jats:italic>mode repulsion</jats:italic>, where the distance between certain modes in the frequency-wavenumber domain is assumed to be a measure of coupling strength. Measurements at different stages of curing of the adhesive layer are performed and evaluated. A comparison of the results shows changes in the dispersive properties, namely an increased modal bandwidth for the fully cured sample as well as an increased modal distance."}],"doi":"10.1515/auto-2021-0089","title":"An approach to adhesive bond characterisation using guided acoustic waves in multi-layered plates","user_id":"11829","main_file_link":[{"url":"https://www.degruyter.com/document/doi/10.1515/auto-2021-0089/html"}],"type":"journal_article","publication":"at - Automatisierungstechnik","quality_controlled":"1","page":"962-969","author":[{"first_name":"Henning","full_name":"Zeipert, Henning","id":"32580","last_name":"Zeipert"},{"id":"11829","last_name":"Claes","full_name":"Claes, Leander","first_name":"Leander","orcid":"0000-0002-4393-268X"},{"first_name":"Sarah","full_name":"Johannesmann, Sarah","last_name":"Johannesmann","id":"29190"},{"first_name":"Yevgeniya","full_name":"Lugovtsova, Yevgeniya","last_name":"Lugovtsova"},{"last_name":"Nicolai","full_name":"Nicolai, Marcel","first_name":"Marcel"},{"last_name":"Prager","full_name":"Prager, Jens","first_name":"Jens"},{"last_name":"Henning","id":"213","full_name":"Henning, Bernd","first_name":"Bernd"}],"department":[{"_id":"49"}],"citation":{"ieee":"H.

Due to real-time constraints, the major\r\nchallenge in MPC is to solve model-based optimal control problems in a very\r\nshort amount of time. For linear-quadratic problems, Bemporad et al. have\r\nproposed an explicit formulation where the underlying optimization problems are\r\nsolved a priori in an offline phase. In this article, we present an extension\r\nof this concept in two significant ways. We consider nonlinear problems and -\r\nmore importantly - problems with multiple conflicting objective functions. In\r\nthe offline phase, we build a library of Pareto optimal solutions from which we\r\nthen obtain a valid compromise solution in the online phase according to a\r\ndecision maker's preference. Since the standard multi-parametric programming\r\napproach is no longer valid in this situation, we instead use interpolation\r\nbetween different entries of the library. To reduce the number of problems that\r\nhave to be solved in the offline phase, we exploit symmetries in the dynamical\r\nsystem and the corresponding multiobjective optimal control problem. The\r\nresults are verified using two different examples from autonomous driving."}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"author":[{"first_name":"Sina","full_name":"Ober-Blöbaum, Sina","last_name":"Ober-Blöbaum","id":"16494"},{"orcid":"https://orcid.org/0000-0002-3389-793X","last_name":"Peitz","id":"47427","first_name":"Sebastian","full_name":"Peitz, Sebastian"}],"title":"Explicit multiobjective model predictive control for nonlinear systems  with symmetries","department":[{"_id":"101"}],"main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/rnc.5281","open_access":"1"}],"oa":"1","user_id":"15694","citation":{"mla":"Ober-Blöbaum, Sina, and Sebastian Peitz. “Explicit Multiobjective Model Predictive Control for Nonlinear Systems  with Symmetries.” <i>International Journal of Robust and Nonlinear Control</i>, vol. 31(2), 2021, pp. 380–403, doi:<a href=\"https://doi.org/10.1002/rnc.5281\">10.1002/rnc.5281</a>.","bibtex":"@article{Ober-Blöbaum_Peitz_2021, title={Explicit multiobjective model predictive control for nonlinear systems  with symmetries}, volume={31(2)}, DOI={<a href=\"https://doi.org/10.1002/rnc.5281\">10.1002/rnc.5281</a>}, journal={International Journal of Robust and Nonlinear Control}, author={Ober-Blöbaum, Sina and Peitz, Sebastian}, year={2021}, pages={380–403} }","short":"S.
